A method for producing granules from a web of plastic, rubber or the like. The granules are cut in one operation from the web, the width of which is substantially greater than the largest dimension of the granules, characterized in that the granules along two cut edges forming an angle to one another in a sequence from one and the other longitudinal edge towards the center of the web or from one and the other end towards the center of a number of width sections of the web and the granules separated in each case free cut edges for the section of the then form granules to be separated. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Schneiden längs der bieden 'Schnittkanten hauptsächlich gleichzeitig mit Beginn an deren Schnittpunkt erfolgt.2. The method according to claim 1, characterized in that the cutting along the two 'cut edges takes place mainly at the same time as they begin at the point of intersection. 3. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß für das Abifennen der Granulate zunächst in der Längsrichtung der Bahn und daraufhin vom Schnittpunkt der Schneidkanten aus in der Querrichtung der Bahn geschnitten wird.3. The method according to claim 1, characterized in that for the Abifennen the granules are first cut in the longitudinal direction of the web and then from the intersection of the cutting edges in the transverse direction of the web. 4. Maschine zur Durchführung des Verfahrens nach Anspruch 1, mit einer Zuführeinrichtung für kontinuierlichen Vorschub der zu verarbeitenden Materialbahn zu einem feststehenden Gegenmesser und einem rotierenden, mit diesem Gegenmesser zusammenarbeitenden Messerzylinder, wobei das Gegenmesser eine parallel zur Messerzylinderachse verlaufende nicht unterbrochene Schneidkante aufweist und auf dem Messerzylindermantel Schneidorgane mit gleichem Schnittradius auf dem Umfang des Messerzylinders versetzt angeordnet sind, dadurch gekennzeichnet, daß die Schneidorgane (32) in der Mantelfläche des Messerzylinders (15) längs eines oder mehrerer Paare gegenläufiger Schraubenlinien angeordnet sind und daß die Schneidorgane (32) jedes Schraubenlinienpaares von einer axial gegenüberliegenden Endpunkten (1, 1) des Messerzylindermantels oder von einer4. Machine for carrying out the method according to claim 1, with a feed device for continuous feed of the material web to be processed to a fixed counter knife and a rotating knife cylinder that cooperates with this counter knife, the counter knife having an uninterrupted cutting edge running parallel to the knife cylinder axis and on the Knife cylinder jacket cutting elements with the same cutting radius are arranged offset on the circumference of the knife cylinder, characterized in that the cutting elements (32) are arranged in the lateral surface of the knife cylinder (15) along one or more pairs of counter-rotating helical lines and that the cutting elements (32) of each helical pair of one axially opposite end point (1, 1) of the knife cylinder jacket or one 2 O 9 8 1 3 / 1 3 U O ΪΓ "*"''""' ":.""*-» °hnß ie(J«2 O 9 8 1 3/1 3 U O ΪΓ "*"''""'":.""* -» ° hnß i e (J « »j.
